TSCA reform and engineered nanomaterials

by Andrew Maynard April 23, 2010

A bit of a wonky blog I’m afraid, but having seen relatively little on the recently introduced Safe Chemicals Act of 2010 and its relevance to engineered nanomaterials on the web, I thought I would post something short and sweet here. Just over a week ago, Senator Lautenberg introduced a bill in the US Senate [...]

Nanotechnology: Weighing the risks of regulation

by Andrew Maynard July 8, 2009

I’m often intrigued by the evolution of an article from its early drafts to the final version.  To complement today’s commentary on nanotechnology regulation in the journal Nature, written jointly with David Rejeski, I thought it would be interesting to post an early draft of the same paper here.  This is what the piece looked [...]

New carbon nanotube study raises the health impact stakes

by Andrew Maynard March 26, 2009

I’m looking at an electron microscope image of a carbon nanotube – as I cannot show it here, you’ll have to imagine it.  It shows a long, straight, multi-walled carbon nanotube, around 100 nanometers wide and 10 micrometers long.  There is nothing particularly unusual about this.  What is unusual is that the image also shows [...]

Confessions of a “media hog”

by Andrew Maynard March 26, 2009

There are some things they don’t cover in media training, like giving interviews while suffering from stomach flu, talking to reporters thousands of miles away while on a dodgy cell phone connection, or speaking intelligently while your three-year-old niece runs rings around your legs.  It’s probably because they come under the “so bloody stupid no [...]

Are we ready for synthetic biology?

by Andrew Maynard March 25, 2009

A new report looks at the challenges of regulating first generation products of synthetic biology. At the J. Craig Venter Institute, scientists are on the verge of creating a living organism from “dead” chemicals, by rebooting a microbe with a new—and completely artificially constructed—genome. At the University of California Berkeley, researchers are modifying microbes to [...]

Biohacking—synthetic biology for the technologically marginalized

by Andrew Maynard December 26, 2008

Last June I wrote a short piece on biohacking, prompted by a UK report on the social and ethical challenges of synthetic biology.  At the time, I though the aspirations of the nascent biopunk community naively optimistic, but potentially worrying.  Six months on, biohacking is hitting the mainstream press—and gaining momentum. Maybe it was just [...]

Taking a fresh look at nanomaterials

by Andrew Maynard November 11, 2008

The Royal Commission on Environmental Pollution report on Novel Materials Imagine for one naïve moment that we have a pretty good handle on managing the environmental impact of existing manufactured “stuff”.  Then someone comes along and invents some “new stuff” that behaves very differently from the “old stuff.” How can we be sure that the [...]

Value-added nanotechnology

by Andrew Maynard September 3, 2008

Amidst the cacophony of debate swirling around the true meaning of nanotechnology, I head a voice or reason last week.  The voice was that of Dr. Bernd Sachweh of BASF, speaking at the European Aerosol Conference in Thessoloniki. I paraphrase, but the essence of Bernd’s point was this: ‘Nano’ is not a thing or a product.  It has [...]

Nano-sunscreens leave their mark

by Andrew Maynard June 21, 2008

Painted metal roofs are cheap, convenient, and usually very durable.  But over the past two years, a rash of accelerated ageing has blighted pre-painted steel roofing in Australia.  And intriguingly the ageing—which affects the coating—seems to be localized to small patches, taking on the form of fingerprints, handprints and even footprints. The culprit it seems [...]

Smart materials; smart choices?

by Andrew Maynard May 31, 2008

Why nano?  Why care?  For non-nanotech initiates, an obsession with nanotechnology must sometimes seem a bizarre occupation of the sad and lonely.  And even within the nanotechnology community, who hasn’t had occasional doubts over the legitimacy of singling out “nano” as something special?  Yet occasionally a piece of work comes along that helps put things [...]

Carbon nanotubes: the new asbestos? Not if we act fast.

by Andrew Maynard May 21, 2008

Mix carbon nanotubes and asbestos together (metaphorically) and you get an explosive mix—at least if news coverage of the latest publication coming out of Professor Ken Donaldson’s team is anything to go by.  The research—published on-line today in Nature Nanotechnology—is the first to explicitly test the hypothesis that long carbon nanotubes behave like long asbestos [...]

Decoupling “nanotechnology”

by Andrew Maynard May 17, 2008

“Nanotechnology” as an overarching concept is great for sweeping statements and sound bites, but falls short when it comes to real-world decision-making.  As nanoscale technologies are increasingly used in everything from antimicrobial socks to anti-cancer drugs, perhaps its time to rethink how we talk about the myriad diverse technologies that fall, slip or are forcibly [...]

Nano-silver: Looking a little tarnished?

by Andrew Maynard May 2, 2008

The author Neal Stephenson got it wrong—at least, if this week’s nano-news is anything to go by!   In his landmark 1995 novel “The Diamond Age,” Stephenson described a future built on nano-innovation.  But thirteen years later, nanotechnology seems to be ushering in “The Silver Age.”  And to some it’s looking a little tarnished. First we [...]

I’m breathing in nanoparticles, so why aren’t I dead already?

by Andrew Maynard April 5, 2008

Read some accounts of nanotechnology risks, and you might be forgiven for concluding that a single engineered nanoparticle can kill you.  Of course, a little critical thinking soon dispels this notion—we are constantly bombarded with incidental nanoparticles from sources that include cars, incinerators and fires; we have been since birth.  And as critics of “risk [...]
